Hybrid multi-terminal direct current(MTDC)transmission technology has been a research focus,and primary frequency regulation(FR)improvement in the receiving-end sys-tem is one of the problems to be solved.This paper presents a decentralized primary FR scheme for hybrid MTDC power sys-tems considering multi-source enhancement to help suppress frequency disturbance in the receiving-end systems.All the con-verters only need local frequency or DC voltage signal input to respond to system disturbance without communication or a con-trol center,i.e.,a decentralized control scheme.The proposed scheme can activate appropriate power sources to assist in FR in various system disturbance severities with fine-designed thresholds,ensuring sufficient utilization of each power source.To better balance FR performance and FR resource participa-tion,an evaluation index is proposed and the parameter optimi-zation problem is further conducted.Finally,the validity of the proposed scheme is verified by simulations in MATLAB/Simu-link.
